{

    private static T instance;

    public static T Instance

    {

        get

        {

            if (instance == null)

            {

                instance = new T();

            }

            return instance;

        }

    }

}

Unity中的mono单例

public class Singleton<T> : MonoBehaviour where T : Singleton<T>

{

    private static T instance;

    public static T Instance { get => instance; }

    protected virtual void Awake()

    {

        if(instance != null)

            Destroy(this);

        instance = (T)this;

    }
